uNrrmSrA RAT TRAP.

"Application ymed yJuly 2,5,

T0 all whom it mcy/'commen' l j Be it known that HovANNEss D ORAKDJAIN, a a citizen of the United States, residing at EastlVatertowmin the county of Middlesex and State of Massachusetts, has invented certain new and useful lmprovements in ification. i j

rlhis invention relatesto rat traps and has for its primary object to substantially improve and simplify over the form of rat trap now in use. y v e An additional object of my invention is to provide such a rat trap wherein the jaw element is maintained in a raised sprung position in a novel and simplified manner, this jaw adapted to be released by both the i weight of the animal upon thetrap platform or by the attempt of the animal to remove the bait from the usual bait impaling hook.

A still further object is to provide such a rat trap that may be manufactured and marketed at small cost, the yinvention comprising relatively few parts and these co-related with cach other as to reduce the possibility of disarrangement to a minimum.

With the above and other objects in view as the nature of the invention is better understo'od, the same comprise the construction, combination and arrangement of vparts set forth in the following specification, shown in the accompanying drawing and claimed. v

In the drawing wherein like reference characters indicatek corresponding parts Ithroughout the several views, and wherein:

lligure 1 is an elevational View of one side of my improved trap, the jaw member theref of being shown inan` unrset position,

Figure 2 is a detaillongitudinal section of the trap, the jaw member being shown in set latched position, and

Figure 3 is a rear elevational view of my trap. i v A Now having particular reference to the drawing, mytrap embodies the provision of e a platform or base board 5 and a vertical backing board 6, which backing board is joined to the edge of said baseboard in a. manner desirable. n

Pivoted adjacent their ends to the klower end of said backing board are the legs 7 of a relatively U-shaped sheet metal jaw member 8, the portions of these legs vbeyond the piv-y otal connections to said backing board being extended downwardly to provide ears 1923. Y serial No. 653,635.

9 as more clearly shown in Figure 1. Loose ly connected to the ends of these ear portions are the inner ends of link rods 10 that extend rearwardly and are looselyconne'cted to the opposite ends of a cross rod 11, Figure 3. The opposite ends of this cross rod extend upwardly as at 12 and terminate in coil springs 13, each of which is rigidly secured 1n a manner preferably as shown'to the oppositesidesof the rear face of said backing board 6. l

v The said baseboard 5 is provided centrally upon its top surface with a channel 14, the bottom wall of whichr is inclined as shown yin Figure 2 and`within said channel 14e, is an animal controlled platform 15 in the formof a strip of sheet metal. The rear end of this platform extends through a passage 16 adjacent the lower end of said backing board l6 and is pivotally secured therein as at 17. Pivotally connected to the pro- "jecting end of said platform is kone end of an upwardly extending rod 18, the upper end of this rod being pivotally connected to one end of a bait hook19 that is pivoted intermediate its ends at 2O within an opening 21 of said backing board 6.` Also kpivotally secured to the projecting end of said bait hook is the lower end of another rod 22 the upper end thereofbeing pivotally secured to the projecting end of a latch member 23 that is pivotally secured within a channel 9A- upon the upper end of the backing board G, it being of course apparent that this latch member 23 serves as a means for maintaintion as shown in Figure 2.

In the operation of my device suitable bait is impaled' upon the hook 19, after which, the jaw 8 is raised to a position paral-.

lel wit-h the backing board G, the same being y.maintained in such position by the latch element 23, it -being of course understood that an upward movement of said jaw will consequently wind up upon the spring elements .13.. A rat or other animal stepping upon the platform 15 will naturally force upwardly upon the rods 18 and 22 for consequently releasing the vlatch element E28 and the Lsprings 13 expanding, the jaw will snap closedthereby trapping the animal.

Should said platform 15 become stuck or otherwise inoperative, the animal tending to A remove the bait from the hook 19 will like- Y wise force said rods 18 and 22 upwardly for accomplishing the same purpose.

Numerous advantages of a trap of this eha laeter will be at onee appreciated by those skilled in the art` and even though I have herein set forth the most praetieal embodiinent of the invention with which I am at the present time familiar7 it is nevertheless to be understood that minor ehanges may be made within the invention without departing from the spirit and Scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A trap including in combination a base board, a baek board fixed to the base board at an angle thereto, u jaw member pivotedl to the lower end portion of the back board and at points between the opposite side surfaces thereof, spring means mounted upon the back board for normally maintaining said jaw closed upon the base board, a platform pivoted to the back board at a point between the opposite side surfaces thereof and disposed over the base board, a bait hook pivoted upon the back boardat a point between the opposite side surfaces thereof and passing transversely therethrough, a lateh ineinber pivoted upon the lower end of said back boa-'rd at a point between the opposite surfaces thereof and adapted to engage the aw to hold the saine open, and a rod disposed alongthe back board and pivotally connected with the plat-form, the bait hook, and the latehing member.

In testimony whereof I aflix my signature.

HOVANNESS DORAKDJAIN.
